Lighting 6-5 Fog Lamps Use the fog lamps for better vision in foggy or misty conditions. The fog lamps button is on the exterior lamps control to the left of the steering column. Interior Lighting Instrument Panel Illumination Control Courtesy Lamps The courtesy lamps automatically come on when a door is opened. The lamps can also be turned on manually by fully turning the instrument panel brightness control clockwise. The reading lamps, located on the headliner above the rearview mirror, can be turned on or off independently of the automatic courtesy lamps, when the doors are closed. # (Fog Lamps): Press the exterior lamps button to turn the fog lamps on or off. A light comes on in the instrument panel cluster when the fog lamps are in use. The ignition must be on for the fog lamps to work. When the headlamps are changed to high beam, the fog lamps turn off. The fog lamps come back on again when the high-beam headlamps are turned off. Some localities have laws that require the headlamps to be on along with the fog lamps. The instrument panel brightness knob is located on the instrument panel to the left of the steering column. Dome Lamps The dome lamps are located in the overhead console and above the rear seat passengers. The dome lamps come on when a door is opened, unless the dome lamp override button is pressed in. D (Instrument Panel Brightness): Push the knob in all the way until it extends out and then turn the knob clockwise or counterclockwise to brighten or dim the lights. Push the knob back in when finished.
